Perylenetetracarboxydiimide (PEDI) molecularly dispersed in polyamic acid (PAA) and polyimide (PI) films has unique fluorescence properties. An originally strong fluorescence of PEDI is efficiently quenched in the PAA films. The systematic variation of the chain structure of the PAA matrices reveale
## Abstract The miscibility and morphology of polyimide/polyimide blends, PEIโE/PTIโEPEIโE: poly(ether imideโether), PTIโE: poly(thioetherimideโether), PBPIโE: poly(biphthalimideโether); cf. exptl. part. and PBPIโE/PTIโE, have been studied by means of ^13^C CPMAS NMR technique. The results indicat
